introduction
K型热电偶用补偿线缆研发
一、热电偶用补偿导线compensating wire in electric thermocouple
(一)执行标准carry out standard：
本产品各项技术指标符合GB4989-1994(等效于IE0584-3)的要求.
Each of products reach the technical indicator accord is better than GB4989-1994 (EC584-3)
(二)使用特性use characteristic：
工作温度：耐热级最高200-260℃ work temperature：Heat-resistin8 grade200-260"C
普通级最高105℃ ordinary grade 105℃
最低环境温度：氟塑料绝缘及护套固定敷设-60℃
The 10west work environmental temperature：The flour plastics insulates and the sheath：It is the regular lay by—60℃
非固定敷设-20℃ it is getting regular to lay-20℃
聚氯乙烯绝缘及护套固定敷设-40℃ www.nodcschoolfordentalassisting.com polyvinyl chloride inns，at：ones and sheath：It sly by-40℃≥固定敷设—15℃ it is getting regular to lay-15℃
(三)产品用途Products use：
补偿导线与热电偶相配套，广泛用于电力、石化、冶金、机电、化工、轻纺、建材军工等厂矿及科研单位的温度测量和系统控制.
The compensate Wire interlock with the electric thermocouple is Wildly，Used in the temperature measurement and control system of the factori9S，mines R&D institution , such as power plants，power stations，metal，orgy，petroleum, chemical industry, iron and steel plant，etc.

(五)分类classifications of compensate wire：
补偿导线按热电动特性的允差不同分为精密级和普通级两种，精密级以“S”表示，普通级略；按使用温度范围分一般用和耐热用两种，分别用“G”和“H”表示.
Compensate-ire according to the difference permit different of divided from accurate grade and ordinary grade accurate grade express With ”S”，the accurate grade according to the temperature range divide with heat-resisting grade and general grade each，respectively express with ”H”and ”G“respectively.
